查询词典 stochastic approximation

Using a decomposition in canonical form, a multi-sensor distributed optimal fusion reduced-order filter for each state component is proposed based on the component fusion algorithm weighted by scalars in the linear minimum variance sense for descriptor discrete stochastic linear systems with multiple sensors. It requires in parallel the calculating of a series of scalar weights.

The research results show:(1) we combine time series method with the dispersed Markov Chains theory of stochastic process, and present a Markov Model based the time series analysis for predicting the precipitation for groundwater resources evaluation. Results show that the time series-Markov Model is efficient, and it has higher accuracy than that of the single model of time series;(2) started from the systematic point of view, we analyze the metabolic process of groundwater, establish the ultimate metabolic equation of groundwater for protecting the water resources, and discuss the value of reducing evaporation for making full use of the water resources;(3) Through a theoretical analysis of the results of the experiments, we draw a conclusion: the critical depth on evaporation of groundwater is in step with the height of the maximal capillary rise of media.

通过理论分析与实验研究，得出主要结论如下：(1)论文将传统的时间序列方法与随机过程马尔可夫预报模型相结合，以预报大气降水量，并用于地下水资源评价，创造性的提出了地下水资源评价中降水量的时序——马尔可夫预报模型；(2)论文从系统的观念出发，分析了地球水循环中地下水代谢过程，建立了旨在保护水资源的地下水极限代谢条件方程，并进一步阐明了减少蒸发量和增加补给量在水资源保护中的重要作用；(3)论文通过实验研究和理论分析，论证了潜水蒸发存在极限埋藏深度，得出了潜水蒸发极限埋深与介质最大毛管水上升高度一致的重要结论。

Secondly, by analyzing basic variables——stochastic cash flow and manager utility function, we gain a proposition (7. 1): If manager is risk averter, then he prefers low risk or riskless and he is satisfied with a basically constant compensation.

资本市场效率越高，企业的股票价格越能反映企业经营情况，因而企业发行股票也就更容易，加上代理人是普遍是避险型的，偏好于股权融资，这样企业的债务比率就会更趋于低负债的资本结构。
